"There is hardly a writer of his period who is so little known in our day and whose poems ran through so many editions in his own day. The reviews praised his works; Gray spoke highly of them; Walpole was all adulation; Mrs. Siddons acted in one of his plays; Reynolds annotated one of his poems; Johnson admitted the power of his satire; and Warton went out of his way to bestow supreme commendation upon his didactic poetry. Works by Mason were done into German, French, and Italian; and more than a score of early biographies testify to the interest in his life and personality."
